I have severe apnea and it’s a nightly war with the machine. I sleep, l knock it off, wake up put it back on, repeat.
That was me for the 1st 6 years. I finally found the “Tap-Pap” mask and controlled the leaks and things are better. It’s a nasal pillow but the mounting is different approach. It uses a mouth piece formed to your upper teeth as the base. It does not leak, any, at all, never. I used it at 18 pressure with no leaks although I am down to 12 and over 85 percent compliant.
